10.3.1.3 Eccentric Discs
The second style of tool is more complex but capable of exerting more force on the
valve than the Knock Out Tool. This style can be used on all sizes of the AR valves in
all of the pump models. The discharge valve is removed first. The valve must be
disassembled with the cage, spring and valve body removed from the fluid cylinder prior
to the seat being pulled. A special hex drive tool will assist in removing the cage from
the seat.
